3 Claims. (Cl. 28-15) The present invention relates to improvements 10a.A suitable spacing of the grooves or notches in looms, more particularlyof small size suitin the warp-spacers has been found to be 22 to ablefor use in the preparation of head work, for the inch. example, in theproduction of belts, girdles, neck- At their lower edges, the centralportions of the 5 laces, bags and the like. end pieces and 11 are cutaway for a portion 5 In the construction of looms of small size parofthe central part of each, as indicated at 1'7 and ticularly suitable foruse in bead weaving, great 17a respectively. Each of the end pieces islikedifliculty has been encountered in securing an wise provided with arectangular slot or mortise, inexpensive construction which can bereadily as shown, for example, in dotted lines at 18 on the 10knocked-down and reassembled, and which is end piece 11 in Fig. 1, theseserving for the inser- 10 both simple and rigid when assembled and whichtion of the tongues formed on the tie plate 12, as will also maintaintension during use of the loom. hereinafter set forth. These slots 18are quite The construction of the present invention is free longrelative to their width and are disposed with from disadvantages in suchlooms as hitherto their longer dimensions substantially parallel toconstructed, being composed of few parts of t pp e es of e e pieces 10and 11. 15 simple and inexpensive construction, being As pointed outhereinafter, the end piece 10 is readily assembled without the use ofnails, bolts p vi ed wi h it ble p r op n n 19 f r or nuts and screws,and being extremely rigid he re p n f h warpa ld n nd when assembled foruse. The invention will be t g t p s 9d.

The end pieces 10 and 11 are Slightconcave Curve, a at a. each formed of plates of suitable material, suchIn assembling the device, the t ues O tenons as metal or preferably, ofhard wood s h as 21 of the tie plate 12 are forced into the narrow'maple.

Theupper edges standing that the principal pieces are of exof the endpieces 10 and 11 at or in proximity to tremely Simple d easily uctedform. the warp-spacers or combs and on either side In the use of theloom, the warp-threads in may be ruled with any suitable graduations, asat any desired number are preferably knotted to- 55 gether at one endand the knotted end of the warp-threads is brought around the outside ofone 01' the end plates, suitably head plate 11, then under the latterthrough the opening 17a on the lower side of the end plate and up fromthe lower side of the tie plate through the opening 23, being held therefirmly by forcing a conical or tapering pin 26 through the opening 23,as shown in Fig. 1. The warp-threads are then drawn across-the spacebetween the warp-spacers 13 and 14 on the end plates, being carefullyspaced upon the warp-spacers, the warp-threads extending between the twoend plates being indicated at 28. At the opposite end, after passingover the warp-spacer 13 on the end plate 10, the warp-threads areseparated in groups and each group is secured to a slotted, taperingtightening pin 19a forced into the tapered openings 19 in the .end plate10. The taper of the openings 19 conforms to that of pins 19a, so that asubstantial bearing and wedging surface is secured. By rotating thesetightening pins, the warpthreads 28 or any part thereof may be stretchedto the desired tightness between the end plates. In stretching thewarp-threads in this manner, the center bar or tie plate 12 is somewhatbowed, and its resilience tends to maintain the warpthreads under thedesired tension.

The construction as herein described and illustrated is composed of fewand very simple parts, all of inexpensive construction and is readilyassembled and disassembled without the use of nuts, bolts, screws, nailsor the like. Furthermore, by reason of the method of assembly employed,the entire device when assembled is of very rigid stable constructionand may hence be employed for the production of bead-fabrics of veryconsiderable widths, say up to '7 to 12 inches. The structure, in use,provides a clear space between the warp-spacers for necessarymanipulation by the weaver and the entire device is free fromobstructions and from projections or parts of a character tending tocatch the threads or otherwise interfere in weaving.

I claim:

1. A bead loom of readily demountable construction capable of beingassembled to form a rigid construction comprising end plates havingwarp-spacers upon their upper edges and being provided with rectangularopenings, and a tie plate extending therebetween, said tie plate havingat each end a projecting tenon adapted to enter and pass through theopening in the corresponding end plate and spaced bearingshoulders onopposite sides of said tenon, and wedge means for forcing the end platesfirmly against the bearing shoulders upon the tie plate whereby the endplates and tie plate are held in rigidly assembled relation.

2. A bead loom of readily demountable construction capable of beingassembled rigidly and comprising end plates having warp-spacers upontheir upper edges and being provided with rectangular openings, a tieplate extending therebetween, said tie plate having at each end aprojecting tenon adapted to enter and pass through the opening in thecorresponding end plate and spaced bearing shoulders on opposite sidesof said tenon, wedge means for forcing the end plates firmly against thebearing shoulders upon the tie plate, whereby the end plates and the tieplate are held in rigidly assembled relation, an opening being providedin the tie plate between the end plates and near one of the latter, a.tapered pin entering said opening for retaining ends of warp-threadstherein, the opposite end plate being provided with a. plurality ofopenings, and tapered pins adapted to enter the last-mentioned openingsfor receiving the corresponding ends of warp-threads and tightening thelatter.

3. A bead loom of readily demountable construction capable of beingassembled to form a rigid construction comprising end plates havingwarp-spacers upon their upper edges and being provided with rectangularopenings, a tie plate extending therebetween, said tie plate being offiat, somewhat flexible and resilient material and having opposite sidessomewhat concave in curvature to increase the flexibility and resiliencethereof, said tie plate having at each end a projecting tenon adapted toenter and pass through the opening in the corresponding end plate andalso having spaced bearing shoulders on opposite sides of said tenon,wedge means for forcing the end plates firmly against the bearingshoulders upon the tie plate whereby the end plates and tie plate areheld in rigidly assembled relation, and means for placing under tensionwarp-threads extending between said warp-spacers, thereby somewhatbowing the tie plate whereby tension is maintained on the warp-threads.
